Put the same player in the line-up twice

You can put the same player (different cards) in the line-up at the same time. Several players have Out-of-position cards which can be used for this.
Here's how it's done:
-Have the one card in the line-up, the other card on the bench
-The second card has to have a lower rated card in its' place
-Press upgrade button

Be aware that this trick might worsen the performance of certain players. Reported cases are of Tom Brady and Tyler Lockett
